Sakura Cyclist With Pastel Road Bike

Create a photorealistic vertical lifestyle portrait of a fashionable young female cyclist posing with an ornate pastel bicycle in a spring park. The subject is {argument name="character name" default="a young woman"} with a softly anonymized, featureless face, shoulder-length {argument name="hair color" default="blonde hair"}, wearing a glossy pink-and-white cycling helmet, a fitted white short-sleeve cycling skinsuit with pale pink side panels and delicate cherry-blossom patterns, a pink bow belt at the waist, white cycling gloves, pink floral socks, and white-and-pink cycling shoes. She stands beside and partly over a custom pearlescent white and pink road bike with drop handlebars wrapped in pink tape, a translucent golden handlebar section, floral decals on the frame, deep carbon-style rims decorated with pink cherry blossoms and petal graphics, disc brakes, a pink chain detail, a small rabbit plush charm hanging from the handlebar, and a dangling rectangular tag with decorative Japanese-style writing near the rear saddle. Include exactly one small dog at the lower left: a Cavalier King Charles Spaniel sitting calmly on the path, wearing a gray harness with a white emblem, looking toward the viewer. Set the scene on a sunlit riverside or lakeside park path during spring, with calm water behind the bicycle, lush green trees, and a large cherry blossom tree blooming on the left. Use warm late-afternoon golden light, soft depth of field, realistic reflections, crisp subject detail, dreamy pastel color grading, high-end fashion editorial composition, full-body framing, no extra people in the foreground, no readable brand logos, no watermark. Emphasize the theme of {argument name="occasion" default="World Bicycle Day"} with a cute, elegant, sakura-inspired cycling aesthetic.
